Type 200 Pre-Cambered Series

Belonging to the HD200/CB200/ZB200 heavy-duty high-strength Bailey system, its overall structural rigidity and load-bearing performance far exceed the conventional 321 series. It is primarily designed for high-strength and ultra-stable heavy-duty construction scenarios. Compared to the 321 model, its overall rated load-bearing capacity is increased by 40%–60%, making it suitable for the passage of ultra-heavy vehicles, large equipment, and long-term continuous heavy-duty conditions. The product covers three major categories: standard, high-strength, and ultra-heavy. The standard pre-camber model is suitable for medium and heavy-duty short-span industrial temporary support structures, meeting conventional heavy construction loads. The high-strength model adopts overall thickened profiles combined with precise pre-camber technology, significantly upgrading its resistance to deformation and fatigue, allowing it to endure repeated heavy-duty operations and dynamic load impacts over a long period. The ultra-heavy model features a fully reinforced structure and customized large camber, specifically tailored for high-load and demanding conditions such as mine heavy-duty access roads, large offshore work platforms, and ultra-high formwork support. It is specially designed for heavy infrastructure projects requiring high loads, high wear, and high stability.

ABOUT JINHAO

Zhenjiang Jinhao Road & Bridge Supporting Engineering Co., Ltd.

Zhenjiang Jinhao Road and Bridge Supporting Engineering Co., Ltd. is located in the industrial park of Shangdang Town, Dantu District, Zhenjiang City, near the Beijing Hangzhou Grand Canal and Yangli Expressway, only 15 minutes drive from Zhenjiang High-speed Railway South Station, with convenient geographical transportation location.
As a professional China Type 200 Pre-Cambered Series Suppliers and Type 200 Pre-Cambered Series Factory, the company was established in 2017 . In the early stage, it was engaged in the professional marketing of construction materials, industrial materials and various metal processing materials. With the expansion of its business scope, our company has transformed into the design, manufacturing, erection, leasing and other comprehensive businesses of Bailey bridge, hanging basket, and pier body formwork. Now, the main products are Bailey steel bridge, 321 types, HD200 type, triangle hanging basket, diamond hanging basket, and various steel templates.
Bailey steel temporary bridge is widely used in national defense combat readiness, traffic engineering, municipal engineering, water conservancy engineering and railway engineering. It is a fabricated bridge widely used in the world. It has the characteristics of simple structure, convenient erection, high standardization, strong interchangeability, various structural forms, large bearing capacity, good applicability, etc. It can be combined into temporary bridges, emergency bridges and semi-permanent bridges of various types and purposes according to different spans. It can also use trusses to conveniently form engineering structures and road and bridge equipment such as guide beams, arches, tower columns, gantry hangers, bridge erection machines, building climbing formwork, etc.
